Dropper Assembly Solution for Mr. Bullet Feeder

Users of Mr. Bulletfeeder know the issue of the dropper assembly using only brass weight to seat a bullet into case. Sometimes this force is not big enough to properly seat a bullet into case.

When I was using Mr. Bullet feeder without MARK-7 this was not so annoying. I got dropped bullet about every 50 rounds so not a big deal. But when I purchased MARK-7 this problem made me crazy and I got a lot of jams and spilled powder.

Our solution to a problem is to increase bullet seating force with spring rather than weight. So upgrade product is born – Dropper Assembly Solution for Mr. Bulletfeeder.

Upgrade kit contains: Custom spring holder tension coil spring and hand knob screw to attach spring and no tool disassembly.

I got running my MARK-7 on XL650 about 5K rounds without bullet drop.
